Abstract

Modularized components assembled dispensing nozzle, including operating components in the category of a poppet valve assembly, an automatic shutoff device, a hand operating lever for providing a turn on or shutoff of the dispensing of fluid through the nozzle, and a connected spout that delivers fluid to the fill pipe and fuel tank for a vehicle or fluid accepting container. Each of the identified components having been redesigned for assembly in modularized form, such as a modular cartridge for the poppet valve, a modular cartridge for the automatic shutoff device, a modularized operating hand lever, and a spout and its gland and retaining nut that provide for high speed interconnection with the nozzle body, during assembly, or servicing. Each of these modularized components can be installed, during assembly of the manufactured nozzle, or can be replaced, out in the field, by a service person, as a modularized component or cartridge assembly.

Claims

1. A modularized components assembled dispensing nozzle comprising:

a nozzle housing body having a flow path there through for the flow of fluid for dispensing to a vehicle or fluid accepting container, the nozzle housing body having a back end having a connector for attachment of a dispensing hose thereto, and the nozzle housing body having a front end;

a poppet housing formed in the nozzle housing body;

a poppet valve assembly for insertion into the poppet housing;

a poppet cap for being threaded into the poppet housing and fitting within the poppet housing and the poppet cap being flush with the poppet housing for containing the poppet valve assembly therein;

an automatic shutoff assembly for insertion into the nozzle housing body;

a cap for covering the automatic shutoff assembly with the cap being fastened to the nozzle housing body;

a spout connected to the front end of the nozzle housing body by use of a retaining nut, the spout for delivery of fluid there through and into a fill pipe of the vehicle or fluid accepting container;

the poppet valve assembly providing for opening of the flow path for allowing fluid to flow through the nozzle housing body for delivery, the automatic shutoff assembly providing for the automatic shutoff of the poppet valve assembly when a fluid tank is filled with delivered fluid, the entire poppet valve assembly being modularized and having a narrowing taper from top to bottom to provide for the entire poppet valve assembly to be delivered into the poppet housing for installation, during assembly or servicing in the field of said dispensing nozzle, or to provide for removal of the poppet valve assembly by removal of the poppet cap during servicing and the entire automatic shutoff valve assembly being modularized and having a narrowing taper from top to bottom to provide for the entire automatic shutoff valve assembly to be delivered into the nozzle housing body for installation, or to provide for removal of the entire automatic shutoff assembly by removal of the cap during servicing in the field; and

said nozzle having an elliptical expansion plug provided along its side, and overlapping the location of the poppet valve assembly and the automatic shut-off valve assembly, such that when said plug is removed, the nozzle may be converted to different styles of dispensing nozzles in preparation for usage.

2. The modularized components assembled dispensing nozzle of claim 1 wherein the retaining nut of the spout further comprises a series of internal segments of threads for securing the spout to the front end of the nozzle housing body, the series of internal segments of threads being arranged diametrically within the retaining nut, the front end of the nozzle housing body having segmented threads diametrically arranged upon an outer surface of the nozzle housing body whereby upon the connecting of the spout by use of the retaining nut to the nozzle housing body the retaining nut threads locate immediately the housing body threads, and within approximately a quarter turn provides for rigid connecting of the spout to the nozzle housing body during installation.

3. The modularized components assembled dispensing nozzle of claim 2 wherein the retaining nut further comprises a series of lands for accommodating the application of a tool to provide for the fastening or removal of the retaining nut from the nozzle housing body during installation or removal of the spout.

4. The modularized components assembled dispensing nozzle of claim 1 wherein the automatic shutoff assembly is entirely modularized, having its reduced tapering configuration along its length to accommodate its installation within the nozzle housing body during assembly or servicing.

5. The modularized components assembled dispensing nozzle of claim 1 wherein the poppet cap comprises a series of segmented threads, the threads being arranged diametrically spaced from each other upon a downwardly extending sleeve of the poppet cap, the poppet housing having corresponding threads placed diametrically from each other and arranged offset from the cap threads, whereby upon application of the poppet cap into the poppet housing a quarter turn of the cap provides for a locking of the poppet valve assembly within the poppet housing.
